In https://github.com/drolbr/Overpass-API/issues/237#issuecomment-927285088I @drolbr showed this handy way to inject the length of a way into the tags of the osm-tags output.

Unfortunately, that breaks osmtogeojson. When I try to convert, I get an empty result

This works

https://olbricht.nrw/ovt/?Q=%5Bout%3Ajson%5D%3B%0Away%5B%22highway%22%3D%22service%22%5D(%7B%7Bbbox%7D%7D)%3B%0Aout%20geom%3B&C=41.89409;12.49391;20&R

[out:json];
way["highway"="service"]({{bbox}});
out geom;

Output

And transforming it via http://tyrasd.github.io/osmtogeojson/ works.

This does not work
